Stroke is either wholly blocked or not blocked, and only one type of input is processed per stroke

[evilC]

There is only one block variable, causing the whole stroke to either be blocked or not.
A stroke can contain one or more of mouse button events, relative movement or absolute movement, but an if/else is used, so only one type of input will be processed per stroke

This causes the following issues:

• When subscribing using block to mouse movement, mouse buttons are blocked, and vice versa
• If multiple mouse buttons are subscribed, but eg only one is blocked, then all will be blocked

Each stroke needs to be split up into multiple strokes, and the if/else changed to multiple unrelated ifs
